Although human land use in the industrial and post-industrial world has had demonstrable impacts on global climate, human land use may also improve or reduce the resilience of ecosystems to anthropogenic and natural climate change. This dissertation tests the hypothesis that low severity anthropogenic burning by prehistoric and protohistoric indigenous societies in the ponderosa pine forests of east-central Arizona improved the resilience of these forests to low frequency climate change. I use sedimentary charcoal, phosphorus, stable carbon isotopes, and palynology to reconstruct changes in fire regimes over the last 1000 years from seven radiocarbon dated alluvial sequences in five watersheds across a gradient of indigenous land use and occupation histories. Paleoecological evidence from occupied watersheds is consistent with small-scale, agricultural burning by Ancestral Pueblo villagers (between AD 1150-1325/1400) and anthropogenic burning by Western Apaches to promote wild pant foods (ca. AD 1550-1900) in addition to naturally frequent, low severity landscape fires. Statistical reconstructions of climate driven fire activity from tree-ring records of annual precipitation indicate that Southwestern forests were vulnerable to increased fire severity and shifts to alternative stable states between AD 1300-1650. In watersheds that were unoccupied or depopulated by AD 1325, paleoecological and sedimentological evidence is consistent with an increase in fire severity, whereas areas occupied and burned by indigenous people until AD 1400 did not yield evidence of increased fire severity. These results suggest that anthropogenic burning by small-scale societies may have improved the resilience of Southwestern forests to climate driven environmental changes.

There is a great variety of software solutions which improve quality of work and increase productivity. Nevertheless there still is a demand for specialized software sollutions, often coupled to particular production systems. In this work author approaches such a concrete subject of computer hardware and repair in small and medium enterprise. Proposed information system not only allows internal administration of service requests within a company, but also provides complete status and process overview for customers accessing company's intranet. This is a unique solution of a kind as others are too general and do not fullfil specific demands posed in the specification. The main subject of this work is software design, development and investigation. Analysis of current software technology platforms was performed and the best deployment platform LAMP (Linux-Apache-MySQL-PHP) was selected. Modular system design provided easy system development and future extendability as well as integration into other portals. Final resulting information system incorporates a number of advanced networking and programming technologies: template engine, certificate based security, data encryption engine and others. Implemented software is customized to meet the needs of particular enterprise and is currently used as part of its' intranet and service network. Legal open source technologies were mostly used for developing the product.

Detta projekt undersöker en praktisk lösning av virtualisering i Ubuntu-server med kvm och virt-manager för användning i en moln- eller Network-as-a-service-miljö. Projektet inkluderar även en jämförelse mellan webbservermjukvaran NginX och Apache2 och en jämförelse mellan videokonferensmjukvaran BigBlueButton och OpenMeetings genom att mäta CPU, Minnes och Nätverksbelastning till de virtuella servrarna vid 1 till 20 uppkopplingar från en klientmaskin. Utifrån projektets resultat rekommenderas Apache2 som webbserver då installationen är enklare och skillnaden i resursanvädning är försummbar och Openmeetings som videokonferesserver då detta alternativ är det mer kompletta.
